Socket Extensions
Flat Blade Screwdriver
10mm Socket
Ratchet
Hi. I'm Mike from 1AAuto. We've been selling auto parts for over 30 years!
To remove the driver's side wiper arm, you leave the hood down, use a small flat blade screwdriver, and gently pry up in this plastic cap. Find the edge and pull it off. There’s a 14mm nut under here. Use a 14mm socket extension and ratchet. Loosen this up. Pull that off. We're going to lift up on the arm and now I'll wiggle it back and forth and it should come right off the wiper arm shaft.
Open the hood. We'll go inside. Pull the release. Find the safety latch. Release that. The prop rod is under the hood. It's got two positions: one position here and then a service position here. It opens further. Passenger side wiper arm has two mounting nuts. They're 14mm. I'm going to use a 14mm socket ratchet again. Loosen that one up and loosen this one up. You might need to hold the wiper arm. Thread it off. It popped right off with just the spring action of the wiper arm. Lift it off the windshield and put it aside.
Put the passenger side wiper arm in place. There was a little dust line here where the wiper blade was, so I'll use that as a reference point. Right about there. There's some spring tension to this that's pushing it back up. I'll install the nuts. I'll just tighten these down until they get tight. I don't want to break off the studs off the wiper transmission.
I'll reinstall the driver's side wiper arm and blade. You could do this with the hood down or the hood up. It's all right. Just get it in place. Reinstall the nut. Tighten it up. If I feel it get tight, I'll stop. I don't want to break the stud off. And reinstall the cap. It just pushes into place.
